#### Linear Features

The default number of hits PC-DMIS generates on a linear feature is a system option. To change this value, access the Setup Options dialog box (Edit | Preferences | Setup), and then click the General tab. Type the new default value in the Auto Line Hits edit box.

PC-DMIS can automatically generate hits for lines and planes. To do this:

1. PC-DMIS must be in Program mode.

2. Move the pointer close to the line.

3. Click the left mouse button.

Follow these rules for measuring linear features:

- PC-DMIS generates equally spaced hits along the length of the line at the current probe depth. (See "Setup Options: General Tab" in the "Setting Your Preferences" chapter for setting the number of hits for lines.)

- The cursor must be placed on the side of the line where the hits are to be taken.

- To automatically program planes, at least two sets of hits at different probe depths must be taken.
